PROGRAM OPTIMIZATION METHOD, PROGRAM OPTIMIZATION PROGRAM, AND PROGRAM OPTIMIZATION APPARATUS

摘要

A program optimization method, executed by an arithmetic processing device, includes collecting profile information including a runtime analysis result by causing a computer to execute an original program to be optimized, calculating a calculation wait time based on the profile information, and generating a tuned-up program, when the calculation wait time is longer than a first threshold, by inserting an SIMD operation control line that performs an SIMD operation for an instruction in IF statement in the loop when an SIMD instruction ratio in the loop in the original program is lower than a second threshold.

1. A program optimization method, executed by an arithmetic processing device, comprising:
collecting profile information including a runtime analysis result by causing a computer to execute an original program to be optimized; calculating a calculation wait time based on the profile information; and generating a tuned-up program, when the calculation wait time is longer than a first threshold, by inserting an SIMD operation control line that performs an SIMD operation for an instruction in IF statement in the loop when an SIMD instruction ratio in the loop in the original program is lower than a second threshold.
